ReviewTracheostomy practice in adults with acute respiratory failure.
Tracheostomy remains one of the most commonly performed surgical procedures in adults with acute respiratory failure and identifies a patient cohort which is among the most resource-intensive to provide care. The objective of this concise definitive review is the synthesis of current knowledge regarding tracheostomy practice in this context. ⋯ In patients who otherwise lack indication for surgical airway, clinicians should defer tracheostomy placement for at least 2 wks following the onset of acute respiratory failure to insure need for ongoing ventilatory support. Subpopulations of patients (e.g., those with acute neurological injury or stroke) may benefit from earlier tracheostomy. Percutaneous dilational tracheostomy should be considered the preferred technique for this intervention in the appropriately selected individual. Future investigations should include efforts to optimize post-tracheostomy management and to quantify tracheostomy effects on patient-centric outcomes.

Multicenter StudyLongitudinal changes in procalcitonin in a heterogeneous group of critically ill patients.
The utility of procalcitonin for the diagnosis of infection in the critical care setting has been extensively investigated with conflicting results. Herein, we report procalcitonin values relative to baseline patient characteristics, presence of shock, intensive care unit time course, infectious status, and Gram stain of infecting organism. ⋯ Procalcitonin dynamics were similar between surgical and medical cohorts. Shock had an association with higher procalcitonin values independent of the presence of infection. Trends in differences in procalcitonin values were seen in patients who had incident vs. prevalent infections.

Continuous electroencephalography monitoring for early prediction of neurological outcome in postanoxic patients after cardiac arrest: a prospective cohort study.
To evaluate the value of continuous electroencephalography in early prognostication in patients treated with hypothermia after cardiac arrest. ⋯ In patients treated with hypothermia, electroencephalogram monitoring during the first 24 hrs after resuscitation can contribute to the prediction of both good and poor neurological outcome. Continuous patterns within 12 hrs predicted good outcome. Isoelectric or low-voltage electroencephalograms after 24 hrs predicted poor outcome with a sensitivity almost two times larger than bilateral absent somatosensory evoked potential responses.

Parental decision-making preferences in the pediatric intensive care unit.
To assess parental decision-making preferences in the high-stress environment of the pediatric intensive care unit and test whether preferences vary with demographics, complex chronic conditions, prior admissions to the pediatric intensive care unit, and parental positive and negative emotional affect. ⋯ Most parents in the pediatric intensive care unit prefer their role in decision making to be shared with their doctor or to have significant autonomy in the final decision. A sizeable minority, however, prefer decision-making delegation. Parental emotional affect has an association with decision-making preference.
